R Program to change a column name of a given data frame

In this Learn by Coding example, we are explaining how to write an R program to change a column name of a given data frame. Here we are using a built-in function data.frame(). A data frame is used for storing data tables which has a list of vectors with equal length. The data frames are created by function data.frame(), which has tightly coupled collections of variables.. The syntax of this function is,

data.frame(…, row.names = NULL, check.rows = FALSE,check.names = TRUE, fix.empty.names = TRUE,stringsAsFactors = default.stringsAsFactors())
– where dots(…) indicates the arguments are of either the form value or tag = value and row. name is a NULL or a single integer or character string.

Two Machine Learning Fields

There are two sides to machine learning:

  • Practical Machine Learning: This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
  • Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
